摘要
目的:探讨分析全冠丝圈和带环丝圈式间隙保持器在单颗乳磨牙早失中的短期临床疗效。方法:选取2020年8月~2021年6月期间在合肥市口腔医院西区儿童口腔科的单颗乳磨牙早失行带环丝圈式保持器和全冠丝圈式保持器的189例患儿临床资料,对其回顾性分析6个月后的临床疗效。将两组基牙新发龋的发病率、基牙牙龈红肿的发病率、间隙保持器生存率(脱落、松动、脱焊)进行临床疗效的对比。结果:全冠丝圈式间隙保持器在基牙新发龋的发病率和保持器生存率上均优于带环丝圈式间隙保持器;以第二乳磨牙作为基牙时,对照组的基牙状态和保持器生存率均优于实验组;第一恒磨牙作为基牙时,对照组的基牙状态优于实验组(P<0.05),两组在基牙牙龈红肿发生率无明显差异,以第一恒磨牙为基牙时,两组的保持器生存率无明显差异(P>0.05)。结论:单颗乳磨牙早失的间隙保持器中全冠丝圈式保持器的临床效果更有优势。
Objective:To investigate and analyze the clinical effect of full crown and band loop space maintainer on premature loss of single deciduous molar.Methods:From August 2020 to June 2021,189 children with premature loss of single deciduous molars restored by band loop space maintainer and full crown space maintainer were analyzed retrospectively.The incidence of new dental caries,the incidence of gingival redness and swelling,and the survival rate of the gap retainer(falling off,loosening,and desoldering)were compared between two groups.Results:The incidence of caries and the survival rate of caries in the full crown group were better than those of band loop space maintainer.When the second deciduous molar was used as the abutment,the abutment status and retention rate of the control group were better than those of the experimental group.When the first permanent molar was used as the abutment,the abutment status of the control group was better than that of the experimental group(P<0.05).There was no significant difference in the incidence of gum swelling between two groups.When the first permanent molar was used as the abutment,there was no significant difference in the survival rate of the retainer between two groups(P>0.05).Conclusion:The full crown space maintainer has more advantages for premature loss of single deciduous molar.
